Detailed Description

Texture class and methods.

Classes
class	fplbase::Texture
	Abstraction for a texture object loaded on the GPU. More...

Typedefs
typedef std::function< Texture *(const char *filename, TextureFormat format, TextureFlags flags)>	fplbase::TextureLoaderFn
	used by some functions to allow the texture loading mechanism to be specified by the caller.

Enumerations
enum	fplbase::TextureFormat {   fplbase::kFormatAuto = 0, kFormat8888, kFormat888, kFormat5551,   kFormat565, kFormatLuminance, kFormatASTC, kFormatPKM,   kFormatKTX, fplbase::kFormatNative, kFormatLuminanceAlpha, kFormatCount }
enum	fplbase::TextureFlags {   fplbase::kTextureFlagsNone = 0, fplbase::kTextureFlagsClampToEdge = 1 << 0, fplbase::kTextureFlagsUseMipMaps = 1 << 1, fplbase::kTextureFlagsIsCubeMap = 1 << 2,   fplbase::kTextureFlagsLoadAsync = 1 << 3, fplbase::kTextureFlagsPremultiplyAlpha = 1 << 4 }
	Flags affecting loading and sampler modes for a texture. More...

Functions
TextureFlags	fplbase::operator| (TextureFlags a, TextureFlags b)
bool	fplbase::HasAlpha (TextureFormat format)
	determines if the format has an alpha component.
bool	fplbase::IsCompressed (TextureFormat format)
	determines if the format is already compressed in some way. If image data is supplied in these formats, we use them as-is.

Enumeration Type Documentation

enum fplbase::TextureFlags

Flags affecting loading and sampler modes for a texture.

Enumerator
kTextureFlagsNone	Default behavior.
kTextureFlagsClampToEdge	If not set, use repeating texcoords.
kTextureFlagsUseMipMaps	Uses (or generates) mipmaps.
kTextureFlagsIsCubeMap	Data represents a 1x6 cubemap.
kTextureFlagsLoadAsync	Load texture asynchronously.
kTextureFlagsPremultiplyAlpha	Premultiply by alpha on load. Not supported for ASTC, PKM, or KTX images.

enum fplbase::TextureFormat

Enumerator
kFormatAuto	The default, picks based on loaded data.
kFormatNative	Uses the same format as the source file.
